摘要： Apparatus and method for in-situ stabilization of unconsolidated sediment in core samples are disclosed. The core sampling apparatus includes a corer having an inner wall, an outer wall, and a plurality of impregnation tubes disposed between the inner and the outer wall, wherein the impregnation tubes are parallel to a central axis of the corer. The method for sampling a core includes extracting a core sample using a corer, and in-situ stabilizing unconsolidated sediment in the core sample within the corer by impregnating the core sample with a resin.

摘要： A method for obtaining geological heterogeneity trends of a geological formation, including the steps: drilling wells (w1, w2, w3, w4, w5) that penetrate the formation, acquiring well logs (log 1, log 2) for each well (w1, w2, w3, w4, w5) as function of depth inter Vals (Dk) of the respective well, determining a third degree tensor (Tk, m, n), where a z-dimension denotes the depths, a x-dimension denotes the well logs, and a y-dimension denotes the wells, extracting matrices (L1k,m, L2k,m, . . . , LMk,n) from the tensor (Tk, m, n), clustering the matrices (L1k,n, L2k,n, . . . , LMk,n) based on the characteristics of the corresponding well logs (log 1, log 2) to a clustering result matrix, aggregating the clustering result matrix to a cluster ensemble (π1, π2, . . . , πM), and spatial partitioning the cluster ensemble (π1, π2, . . . , πM) to a map that shows the geological heterogeneity trends associated with cluster types of the wells (w1, w2, w3, w4, w5).

摘要： Methods of the present disclosure may include obtaining an origin fluid having a calcium concentration of about 1.5 M or greater. A treatment fluid may be created by introducing an amount of slaked lime to the origin fluid to change a pH of the resulting treatment fluid to about 11 or greater. The treatment fluid may be introduced into a subterranean formation containing a formation gas comprising natural gas and carbon dioxide. The calcium in the treatment fluid may be allowed to react with the carbon dioxide within the subterranean formation to form calcite. The treated formation gas may be removed from the subterranean formation after the formation of calcite, wherein the concentration of carbon dioxide in the treated formation gas is lower than the formation gas before it was contacted with the treatment fluid.

摘要： Systems and methods include a method for providing, for presentation to a user, a graphical user interface (GUI) for defining and generating machine learning-based proxy models as surrogates for process-based reactive transport modeling (RTM). User selections of training parameters for generating training sample data are received. The training sample data is generated in response to receiving a parameter files generation indication. A training cases generation indication is received. Training sample cases are executed using the training sample data. User selections of proxy models training parameters are received. A set of parameter-specific proxy models represented by a neural network are trained. Each parameter-specific proxy model corresponds to a specific RTM parameter from a set of RTM parameters. Blind tests are performed using the set of parameter-specific proxy models. Each blind test tests a specific one of the parameter-specific proxy models. Predictions are generated using the set of parameter-specific proxy models.

摘要： Embodiments provide a method for evaluating a hydrocarbon-bearing formation. The method includes the step of identifying a hydrocarbon sweet spot. The identifying step includes determining a carbon dioxide content of a gas sample retrieved from the hydrocarbon-bearing formation. The identifying step includes determining an isotopic signature of carbon dioxide of the gas sample. The carbon dioxide content of the gas sample retrieved from the hydrocarbon sweet spot can have a mole percentage ranging from 9 percent to 20 percent. The isotopic signature of carbon dioxide of the gas sample retrieved from the hydrocarbon sweet spot can have a δ13C value greater than −10 per mil. The identifying step can further include determining a cutoff range of the carbon dioxide content corresponding to the hydrocarbon sweet spot. The cutoff range can have a mole percentage ranging from 9 percent to 20 percent. The identifying step can further include obtaining a gas flow rate of the hydrocarbon-bearing formation. The gas flow rate can be greater than 10 million standard cubic feet per day.

摘要： Petrographic data of a carbonate reservoir in a subterranean region is received. Mud content of the carbonate reservoir is determined based on the petrographic data. A depositional porosity of the carbonate reservoir is computed based on the mud content. An amount of cementation of the carbonate reservoir is determined. A porosity loss by compaction of the carbonate reservoir is determined based on the mud content and the amount of cementation of the carbonate reservoir. A post-compaction porosity of the carbonate reservoir is computed based on the depositional porosity, the mud content, the amount of cementation, and the porosity loss by compaction.

摘要： A method related to generating a facies-cement model of a subsurface region. The method includes obtaining depositional data regarding the subsurface region, wherein the depositional data incudes wave impact data. The method further includes generating, by a computer processor, a geological model for the subsurface region using a forward-depositional modeling process and the depositional data, wherein the geological model comprises wave energy data. The method further includes determining, by the computer processor, carbonate cementation data for the subsurface region using a diagenetic modeling process and the wave energy data, wherein the carbonate cementation data describes cementation in one or more depositional processes, and generating, by the computer processor, a facies-cement model of the subsurface region.

摘要： A method for evaluating reservoir quality of a carbonate rock includes: acquiring a thin section of the carbonate rock with a predetermined thickness; obtaining a microscopic image of the thin section; analyzing the microscopic image of the thin section to determine a content of one or more components of the carbonate rock selected from a group of calcite, pore space, replacive dolomite, dolomite cement, and matrix; and calculating a change of porosity based on the content of the one or more components.
